Windows File Explorer Not Showing Correct Folder Size If Folder Named 'Applications'

Since installing the 1803 update, Windows File Explorer doesn't display the correct folder size if the folder is named 'Applications'.

There seems to be a bug that if the folder name is 6 characters or more and starts with 'Appli', the folder size shows significantly less than it actually is.  For example if the folder is named 'Apps' or 'Appli', it will display the size correctly.  If however it is named 'Applications' or 'Applix' or 'Appliy', then it won't display correctly.

The Feedback app doesn't work on my computer due to having telemetry settings set to 'Basic', therefore I am reporting the bug here instead.

OS Version:

Windows 10 Pro X64 (17134.1, 1803)

    I replaced a customers laptop HDD today, was transferring back his data (100 gigs of photos and movies (.mov and ;jpg files)  I have 1803 on my PC where I had his data backup, I had installed 1709 on his laptop, which was downloading updates at the time of the transfer. My PC told me I was transferring 57 gigs of data, when I looked at the laptop after 3 minutes the progress bar told me I had 99 gigs remaining! 

    Imagine my surprise!

    I went back and checked, if I highlight all the individual files in a folder I get the correct size, If I ask for that folder's size I get a much smaller number. Folder and file types seem to have no impact on the issue. Notice that  the folder "Charlie***" shows 500 megs but when I open it and highlight the folders in it  it shows 57 gigs....Which is ALSO  wrong! There iare over 100 gigs in that folder

    LOL, Good luck :)

    I have exactly the same problem. I have seen this before some versions of Windows ago. Looks like they reintroduced this problem. The funny thing is when I move the directory to another directory and then ask for the size I get another size (still not the proper one).  When I move it to a directory that i just created I get the wrong size. There seems to be a problem with newly created directories since build 1803. 

    Did some test: It has definitely something to do with the name of the directory above the one  you are asking the file size off. When I rename that directory to something completely different I remove the problem. When I rename it back I have the problem again.

    Did some more testing. The problem is worse when the name of the directory above is longer then 8 bytes. below 8 bytes I get more data reported then above 8 bytes but still not the proper amount. This is very weird.

    I'm also seeing this and the folder name doesn't matter. Just started recently. It's occurring on a Samsung 970 SSD. This is the Windows 10 system drive. 

    Top folder says there are 38,690 files. If I open the folder, select all subfolders and do properties, the new values is 90,330 files. If I open the first subfolder and select its subfolders, I get 100,215 files!

    A serious problem.

    I'd guess it's related to path name length.
